The configuration of the attrition mill's agitator system causes constant motion of material around the tank. The area of greatest media agitation is located approximately two-thirds the radius from the center shaft (Figure 2). In production-sized units for wet milling, a pumping circulation system augments the movement.

In a dual-stage hammer mill, there are really three phases of size reduction, due to what is known as the attrition zone. The attrition zone is the area created between the top rotor and bottom rotor of a dual stage hammer mill. Materials pass through the initial mill and screen arrangement and are then directed toward the secondary mill chamber.

The introduction of lower temperatures during cryomilling curbs recrystallization and embrittles materials so they can be fractured more easily with mechanical milling. Cryogenic grinding is often performed in impact mills and hammer mills, but the use of an internally agitated ball mill, like an Attritor, can provide additional benefits.

The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling media. For example, in 10 hours of milling, specific surfaces of 40 and 25 m 2 /g were obtained for alumina and barite, corresponding to 38 and 56 nm equivalent spherical diameter, respectively.
